carry it with you, if you stink the busdriver can ask to search your bags, but you dont have to let him. you will be kicked off the bus though and just catch the next one. dont drink too much either, the one time this happened to me i spent a night in atlanta partying it up, i had half a fifth in my bag left over. the busdriver asked too search my bags because he could smell the booze on me and thought i was drinking on the bus(which is a nono). i told him no and was kicked off untill i could catch another one. i ended up getting the same driver again, he gave me a dirty look about getting on his bus, but couldnt do anything because i was sober.
